[1mint rfio_readlink (const char *[4m[22mpath[24m[1m, char *[4m[22mbuf[24m[1m, int [4m[22mlength[24m[1m)[0m

[1mrfio_readlink [22mgets the content of the symbolic link identified by [4mpath[24m.

[4mbuf[24m content is not null terminated.
Symbolic link content can be truncated to [4mlength[24m if [4mbuf[24m is too small.

This routine returns the count of bytes placed in [4mbuf[24m if the operation
was successful or -1 if the operation failed. In the latter case, [1mser-[0m
[1mrno [22mis set appropriately.

[1mENOENT [4m[22mpath[24m does not exist.

[1mEACCES [22mSearch permission is denied on a component of the [4mpath[0m

[1mEFAULT [4m[22mpath[24m or [4mbuf[24m is a NULL pointer.

[1mENOTDIR [22mA component of the [4mpath[24m prefix is not a directory.

[1mEINVAL [4m[22mpath[24m is not a symbolic link or [4mlength[24m is not positive.

[1mENAMETOOLONG [22mThe length of [4mpath[24m exceeds [1mCA_MAXPATHLEN [22mor the length of
a path component exceeds [1mCA_MAXNAMELEN[22m.
